Help: Featherduster or Apastia?

[Der_Iron_Chef]

Looks like featherdusters to me. Aiptasia only seem to disappear like that when you poke them

I've got lots of dusters that look just like that. I've also had aiptasia and it doesn't look like that.

Thanks, I'll leave them alone then. They are on underside of a ledge in my tank.

Duster I would agree.

yeah looks too frilly to be an anemone (look close for distinct tentacles). I vote duster too.

I say it looks like one of those ever elusive hedgehogeda saltwaterous!
